Hello & welcome,
Not sure of any foz owners that way on her but you could try uk foz too,
Runing costs aren't too bad if you find a local specialists,
With a six mile commute you'll only really get mpg in the low 20's on longer runs expect high 20's early 30's
Only other things really is servicing, an independent will be roughly half the cost of subaru,
Typical costing breakdowns are dependant on your garage but rough prices are
Clutch 300-400
Major service 350-500
Cambelt 350-450
The rest of the parts are relatively cheap and widely available, and if you like working on your own car then they are fairly easy to do.
